fix: show md rules and prompts in respective sections

[uinstinct]

Description

Previously the markdown prompts were showing under the rules sections. This was happening because rules extractor was picking up prompts from the prompts folder also. This PR fixes it.

@uinstinct the invokable property means prompts and rules are the same underlying markdown and rules that are not invokable in the prompts directory will be stranded. I believe this is the original reason they were both read. You should be able to categorize based on invokable rather than changing the directory reading.

@tomasz I remember you had done some thinking on this, does that sound right?

@uinstinct @RomneyDa I think this PR is only partially correct. Picking up rules from the prompts folder (and vice versa) is expected and was added in this PR: #8073

I looked at the Linear ticket and the requirement is If 'invokable: true' is present, it should only show up under prompts and not rules. I believe the behavior of loading rules and prompts from both directories should remain.
